Marc Sorini got his first taste of life as an alcohol lawyer two decades ago as a young attorney working for the California winery that makes the wine known as "Two-Buck Chuck." Sorini, now head of McDermott Will & Emery's alcohol regulatory and distribution group in Washington, was part of the legal team for Bronco Wine Co., which produces Trader Joe's Charles Shaw label - commonly known as Two-Buck Chuck. The winery was facing off against regulators who claimed the brand name of a wine, Rutherford Vineyards, was misleading because it did not reflect the region where the grapes were grown.
